I think you can use ACLs to match the outgoing IP selection based on the
incoming IP.

http://www.squid-cache.org/Versions/v2/2.6/cfgman/tcp_outgoing_address.html

So you could do something like:

http_port 1.1.1.1:3128
http_port 2.2.2.2:3128
http_port 3.3.3.3:3128

acl dstip1 myip 1.1.1.1
acl dstip2 myip 2.2.2.2
acl dstip3 myip 3.3.3.3

tcp_outgoing_address 1.1.1.1 dstip1
tcp_outgoing_address 2.2.2.2 dstip2
tcp_outgoing_address 3.3.3.3 dstip3

Maybe? I haven't tested it.
